无法从URL NBA统计信息中获取数据 [英] Cannot fetch data from URL NBA stats

问题描述

我在从stats.nba.com端点获取JSON数据时遇到问题.例如，此网址 http://stats.nba.com/stats/teamgamelog?LeagueID=00&Season=2016-17&SeasonType=Regular+Season&teamid=1610612761 在我的浏览器中工作正常，但是当我尝试阅读时放入R，我收到错误消息.

I'm having an issue fetching JSON data from the stats.nba.com endpoints. For example, this url http://stats.nba.com/stats/teamgamelog?LeagueID=00&Season=2016-17&SeasonType=Regular+Season&teamid=1610612761 works fine in my browser, but when I try to read it into R, I receive errors.

jsonlite::fromJSON，RJSONIO::fromJSON，RCurl::getURL，HTTR::get都永远挂起，直到我杀死它们.

jsonlite::fromJSON, RJSONIO::fromJSON, RCurl::getURL, HTTR::get all hang forever until I kill them.

rjson::fromJSON给我一个错误意外字符'h'"

rjson::fromJSON gives me an error "unexpected character 'h'"

我不确定是否存在拒绝程序访问的方法，以及如何解决该问题.

I'm not sure if there is something denying programmatic access, and how I would get around that.

R version 3.3.3 (2017-03-06)
Platform: x86_64-apple-darwin13.4.0 (64-bit) 
Running under: macOS Sierra 10.12.3

locale:

推荐答案

在尝试处理文件之前，请先下载文件:

Try downloading the file first before trying to process it:

library(curl)
library(jsonlite)

curl_download("http://stats.nba.com/stats/teamgamelog?LeagueID=00&Season=2016-17&SeasonType=Regular+Season&teamid=1610612761", "nba.json")
jsonlist<-fromJSON( "nba.json")
df<-as.data.frame(jsonlist$resultSets$rowSet)
names(df)<-jsonlist$resultSets$headers[[1]]
parameters<-jsonlist$parameters
